7+ Calc: How to Calculate Free Water Deficit Easily

The determination of the difference between the total body water considered normal for a patient and the patient’s current total body water is a crucial step in addressing hypernatremia. This value, often expressed in liters, guides therapeutic interventions aimed at safely correcting sodium imbalances. The calculation involves several key factors: the patient’s weight (in kilograms), the serum sodium concentration (in mEq/L), and the desired or target serum sodium concentration. A formula incorporating these variables, often using a standard estimate of total body water as a percentage of body weight (e.g., 0.6 for men, 0.5 for women), enables clinicians to estimate the amount of free water needed to achieve the target sodium level. For instance, a 70kg male with a serum sodium of 160 mEq/L aiming for a sodium level of 140 mEq/L would require a specific amount of free water, calculated by substituting these values into the relevant equation.

Accurately estimating this volume is paramount in managing patients with hypernatremia. Rapid or excessive correction of hypernatremia can lead to cerebral edema and neurological complications.
